I dont have time to take those screenshots, but my mac just makes things go a lot more smoothly-
i.e. for connecting to wireless, my mac does that completely automatically without me even clicking a dialogue box. sometimes on my pc laptop the wireless network doesnt get connected to even though its default etc etc.

spyware. oh my gosh spyware. Everytime I browse the net and I dont run adaware for a while my computer runs extremely slow. because of stupid spyware.

defragmentation- my windows harddrive doesn't defrag itself like a mac harddrive so things run slow after a few weeks.

Network places is possibly the most unfinished, annoying and horribly broken feature in Windows generally. I spent a whole day simply setting up file sharing between two PCs, all I need to do is access the hard drive of the other from this one, and the other way around, easy you'd think... ohhhhhh no!

I multitask when I'm computing. Any more than three or four programs at once and Windows starts pausing, doing really slow screen redraws and just grinding to a halt. I find that too frustrating and end up swearing at the computer rather than working.
